“…For a more detailed description see Hébert et al 5 Three different heights of CNTs (1 mm, 2 mm, and 3 mm) were coated with 25 nm boron-doped diamond. As control, at nanocrystalline diamond (NCD) structures as described by Hébert et al 20 were used. One sample of the DCNTs (1 mm) and one control sample can be seen in Fig.…”

“…Rigid diamond microelectrode arrays showed the properties of the diamond combined to that of microelectrodes. They were first used for electrochemical sensing [146][147][148][149][150][151] and were more recently suggested and tested for neural interfacing [152][153][154][155][156][157]. Moreover, despite the high growth temperature of diamond some teams managed to transfer BNCD electrodes on polymer substrates in order to create flexible devices [158,159].…”

Diamond is wide band gap semiconductor presenting many extreme properties. It is notably known as the most stable material with the highest chemical inertness, the highest mechanical hardness and the highest thermal conductivity [1-3]. Since the mid 1970s it has been possible to grow synthetic diamond by several methods. High Pressure High Temperature techniques that mimic the diamond formation in the earth's crust were first developed [4-6]. Then Chemical Vapour Deposition (CVD) methods enable diamond growth at laboratory scale [7-9] as well as the control the P-type and Ntype doping of diamond [10-13]. Besides, it is possible to tune the diamond electrical properties form very resistive to metallic thanks to the P-type doping with boron [14]. Current achievements have enabled the development of diamond sensors that can operate in extreme conditions [15-17]. After being used for its mechanical and thermal properties, diamond was considered for chemical sensing. In fact the chemical stability and the close-to-metallic conductivity of diamond make it a powerful tool for electrochemical detection in various environment. Furthermore, the diamond is an ideal substrate for surface functionalization thanks to the wide and very known carbon based chemistry. Such a feature combined to the outstanding electrochemical properties of the diamond electrodes have enable the production of very efficient biosensors and biochips. Diamond is also an interesting sensor for medical imaging. Its carbon nature, well tolerated by living tissues, are actually very useful for its use as a biosensor capable of working in contact with bio-environments as well as real neuronal interfaces. Both those topics will be discussed in details in the following pages. In a first part an overview on electrochemical based biosensors and their performance is described. Then in a second half of the chapter, novel applications where diamond is directly used as an electrode for neural tissue interfacing is presented in details.

“…In this perspective, the field of boride clusters essentially is very rich. As doping of the bulk metal clusters with boron diversifies the physical and electronic properties, this can be utilized as common strategy for studying both the electronics as well as surface chemistries of the metal borides [19][20][21][22][23][24][25][26][27][28][29]. Several reviews and articles have demonstrated that the area of metal-rich metallaboranes as well as boron-rich metallaboranes are expanding briskly .…”

A number of heterometallic boride clusters have been synthesized and structurally characterized using various spectroscopic and crystallographic analyses. Thermolysis of [Ru3(CO)12] with [Cp*WH3(B4H8)] (1) yielded [{Cp*W(CO)2}2(μ4-B){Ru(CO)3}2(μ-H)] (2), [{Cp*W(CO)2}2(μ5-B){Ru(CO)3}2{Ru(CO)2}(μ-H)] (3), [{Cp*W(CO)2}(μ5-B){Ru(CO)3}4] (4) and a ditungstaborane cluster [(Cp*W)2B4H8Ru(CO)3] (5) (Cp*=η5-C5Me5). Compound2contains 62 cluster valence-electrons, in which the boron atom occupies the semi-interstitial position of a M4-butterfly core, composed of two tungsten and two ruthenium atoms. Compounds3and4can be described as hetero-metallic boride clusters that contain 74-cluster valence electrons (cve), in which the boron atom is at the basal position of the M5-square pyramidal geometry. Cluster5is analogous to known [(Cp*W)2B5H9] where one of the BH vertices has been replaced by isolobal {Ru(CO)3} fragment. Computational studies with density functional theory (DFT) methods at the B3LYP level have been used to analyze the bonding of the synthesized molecules. The optimized geometries and computed11B NMR chemical shifts satisfactorily corroborate with the experimental data. All the compounds have been characterized by mass spectrometry, IR,1H,11B and13C NMR spectroscopy, and the structural architectures were unequivocally established by crystallographic analyses of clusters2–5.
